Microarray studies within the PFC and HYP have also found significant reductions in expression of genes within the ETC, such as NDUFS7 and NDUFS8.18,19,30 However, a recent finding by Gandal et al.31 utilizing RNA-sequencing demonstrated no difference in the expression levels of NDUFS7 and NDUFS8 in cortical tissue of patients with BD,31 emphasizing the complexity and heterogeneity of BD. The gene discussed is NDUFS7; the disease is Behcet disease.
